Wireline seal lubrication systems use automated grease pumps with pressure feedback. The pump maintains injection at 200 psi above well pressure. Grease consumption is monitored to detect seal wear. These seals reduce operational risk in long-duration memory logging jobs. They support extended surveys in high-temperature wells where manual intervention is impractical due to surface te... https://globalsealstech.com/product-category/oil-gas-seals/oil-free-lubricated-pump-seals/
